Administration of various fractions of the extract with CCl4 showed protective ability against CCl4 intoxication by restoring the cardiac functions alterations, activities of antioxidant enzymes and lipid peroxidation in rat.
Broadly, my research is focused on determining how alterations in activity of a transcription factor can have wide-ranging downstream effects on multiple cellular pathways and other regulatory mechanisms (miRNAs) in healthy and disease states.
Severe inflammation is accompanied by alterations in activity of the neuroendocrine system.
The extreme high temperature would induce specific membrane damage, expression of HSP [ 49], and alteration of activity of enzymes, which was not prevalent at moderate heat stress [ 50].
However, it can transiently change to relatively oxidized or overly reduced states upon alterations in activities of photosynthesis or respiration, or upon exposure to external factors.
Acute ammonia intoxication is known to cause alterations in activities of several membrane bound enzymes like Na+ K+ ATPase, acetylcholine esterase and glutamate uptake in brain.
Presented changes in sphingolipid levels are secondary to alterations in activities of enzymes regulating SM and ceramide metabolism.
These diabetes-induced alterations in activities of mitochondrial complexes and energy status could contribute to the underlying role of oxidative stress in the pathogenesis of diabetic nephropathy.
The respective NSAIDs might interfere directly with the transcription factors, but their effects are probably mediated predominantly through alterations of the activity of cellular kinases such as IKKβ, Erk, p38, or mitogen-activated protein kinase [ 51].
The mechanisms responsible for central fatigue are not well understood; though research involving exercising rodents suggests that prolonged physical activity is associated with widespread alterations in the activity of neurotransmitters such as serotonin, dopamine and noradrenaline3,4,5.
